I-SS904L AISI 904L Stainless Steel (UNS N08904)

Incazelo emfushane:

I-UNS NO8904, evame ukubizwa ngokuthi 904L, iyinsimbi engagqwali ephansi ye-carbon high alloy austenitic esetshenziswa kakhulu ezinhlelweni lapho izakhiwo zokugqwala ze-AISI 316L ne-AISI 317L zinganele. I-904L inikeza ukumelana okuhle kokugqwala kokucindezeleka kwe-chloride, ukumelana nomgodi, nokumelana nokugqwala okujwayelekile okungaphezu kuka-316L kanye no-317L we-molybdenum ethuthukisiwe izinsimbi ezingenasici.

Isingeniso Somkhiqizo

I-AISI 904L insimbi engagqwali (UNS N08904) iyi-alloy high austenitic steel stainless steel. Uma kuqhathaniswa ne-316L, i-SS904L inokuqukethwe kwekhabhoni (C) ephansi, okuqukethwe kwe-chromium (Cr) ephezulu, futhi cishe okuphindwe kabili kokuqukethwe kwe-nickel (Ni) ne-molybdenum (Mo)316L, okuyenza ibe nokumelana nokushisa okuphezulu kwe-oxidation, ukumelana ne-pitting, nokumelana nokunciphisa i-asidi (isb, i-sulfuric acid). I-Nitrojeni (N) inganciphisa izinga lemvula ye-chromium carbide, ngaleyo ndlela yehlise ukuzwela kokuzwela, futhi ithuthukise ukumelana nokugqwala nokugqwala okubangelwa ama-chloride. Ikakhulukazi ukungezwa kwayo kwethusi (Cu) kwenza kube usizo kukho konke ukugxila kwe-sulfuric acid.

I-alloy 904L isebenza kangcono kunezinye izinsimbi ezingenasici ze-austenitic ngenxa yokuhlanganiswa okuphezulu kwe-nickel ne-molybdenum. Ibanga alinawo uzibuthe kuzo zonke izimo futhi linokwakheka okuhle kakhulu nokushisela. Isakhiwo se-austenitic siphinde sinikeze leli banga ukuqina okuhle kakhulu, ngisho naphansi kwamazinga okushisa e-cryogenic Okuqukethwe kwe-chromium ephezulu kukhuthaza futhi kugcine ifilimu ye-passive evikela izinto ezibonakalayo ezindaweni eziningi ezigqwalayo. Abukho ubungozi bokugqwala kwe-intercrystalline ekupholiseni noma ekushiseleni ngenxa yokuqukethwe kwekhabhoni ephansi. Izinga lokushisa eliphezulu lesevisi yalo liku-450°C. Leli banga liwusizo ikakhulukazi ekulawuleni nasekusetshenzisweni kwamashubhu wezinsimbi lapho i-316 ne-317L ingafaneleki.

Ingxubevange 904L ekuqaleni yasungulwa ukuze imelane nezindawo eziqukethe i-dilute sulfuric acid. Iphinde inikeze ukumelana okuhle kwamanye ama-asidi angaphili njenge-hot phosphoric acid kanye nama-acid amaningi e-organic.

I-alloy 904L ishiselwa kalula futhi icutshungulwe ngezinqubo ezijwayelekile zokwenziwa kwezitolo.

I-904L insimbi engagqwali (SS904L) isetshenziswa ku-petroleum, amakhemikhali, umanyolo, imibhoshongo yokuthuthukiswa kwasolwandle, amathangi, amapayipi namashubhu kanye nezishintshisi zokushisa. I-Rolex nabanye abakhiqizi bamawashi nabo bayayisebenzisa ukwenza amawashi
